Minor Revision No. 289 (MR289) Adequacy Review No. 1
Dear Mr. Nettleton:
The Colorado Division of Reclamation, Mining, and Safety (Division) received the MR289 application on
August 4, 2015. The Division deemed the application complete on August 25, 2015. The decision date
for the application is September 4, 2015. The following items will need to be addressed prior to the
approval of the revision:
1. Revised page 2.04-9.1 is currently also being revised with MR287. Given that the decision date
for MR287 and MR289 are the same date and to avoid confusion; please revise this page to
include the text from both revisions. Specifically, the section regarding the WCR Coal
Coreholes currently does not match the text submitted with MR287. Please revise this page to
include this information.
2. Proposed revised page 2.05-45.28 indicates that the Cultural Resource Survey for the proposed
activity is located in Exhibit 6T. However, as this survey also includes portions of the MR287
disturbed area, TC has indicated with MR287 that this survey would be placed in Exhibit 6L.
Please revise this page to indicate this survey will be placed in Exhibit 6L.
3. Revised page 2.05-45.28 and 2.05-84.13 indicates 1 foot of soil material will be salvaged from
the borehole pad and that a maximum of approximately 1,500 cubic yards of soil will be
recovered. Exhibit 53-M6 and M7 maps indicates the borehole pad area is 1.2 acres. Given this,
the Division estimates about 1,900 cubic yards of soil should be recovered. Please revise these
pages to increase the estimated amount of soil to be recovered. Also, please revise Table 49A.
4. Please depict the upgradient diversion ditch to be installed on the north and east side of the pad
on the Exhibit 53-M6 and M7 maps submitted.
5. Enclosed is a copy of the reclamation cost estimate the Division conducted for this proposed
project. Please acknowledge if TC concurs with the Division's estimate attached.
